Knee replacement: a clinical review.

چکیده
THE first successful knee arthroplasty was reported in 1861, but from then until the 1940s arthroplasty of the knee was of the interposition type using either autogenous tissue or a foreign non-metallic material between the joint surfaces. Results of this operation were at best poor and unpredictable when compared to arthrodesis, the alternative procedure for degenerative arthritis. Arthrodesis sacrificed movement in order to achieve a predictable clinical result which was very acceptable to both patient and surgeon. Arthrodesis achieved complete pain relief, a stable limb, opportunity to correct deformity and a low complication rate. Metallic interposition arthroplasty began in the 1940s, but again results remained poor. Infection both immediate and delayed was a frequent and devastating complication. Prostheses loosened due to poor bone to metal fixation, high friction forces in the metal on metal joint, and the inherent constraints designed to prevent excessive movement. All these complications hampered early attempts to develop a successful alternative to the stiffening procedure.

The surgical management of Knee Osteoarthritis (KOA), so far, mainly revolved around arthroscopic procedures,arthroplasty (total: TKA and unicompartmental: UKA) or high tibial osteotomy (HTO). Recently, another minimallyinvasive surgical treatment of proximal fibular osteotomy (PFO) has been proposed for the management of KOA. ThePFO has been found to be useful in the manageme...

Abstract Introduction: The presence of cruciate ligaments are very important for normal knee kinematics. Knee arthroplasty prostheses, in which these ligaments are maintained, have better kinematics. The aim of the present study was to investigate the association between femoral intercondylar notch narrowing in radiography and clinical and histopathologic integrity of anterior cruciate li...
